Cable Standards for Integrated PV, Storage and Charging Systems

This document provides comprehensive technical requirements and standards for cables used in integrated photovoltaic (PV), energy storage, and electric vehicle (EV) charging systems. It covers three main areas: cables for PV power generation systems, battery energy storage systems, and new energy vehicle charging systems. The document compares key standards including 2PfG 1169/08.2007, EN 50618:2014, and IEC 62930:2017, detailing differences in product models, rated voltages (DC up to 1.5kV), conductor specifications, insulation materials, and test requirements such as ozone resistance, thermal elongation, and halogen content. A significant focus is on the introduction of IEC 62930, including thermal life evaluation using Arrhenius curves and aging time design principles. The document also addresses aluminum alloy conductor photovoltaic cables, discussing their application, technical challenges (e.g., tensile strength, copper-aluminum connection), and performance requirements. A new standard, TUV Rheinland's 2PfG 2642/01.22, is introduced for aluminum alloy conductors, specifying code designations, conductor classes (Class 1, 2, 5), preferred diameters, and mechanical properties including tensile strength, elongation, bending, and compressive creep tests.
